This is just a debug message output and should have no impact on the
cpufreq driver.
Please try the patch at

So the cpufreq problem is already fixed, right?
Thanks,
Rui

Hi Andrew,
this is already reported in
http://bugzilla.kernel.org/show_bug.cgi?id=8630
and
http://bugzilla.kernel.org/show_bug.cgi?id=8570
Seems the issue was somehow related to my bios, but i don't understand
why windows worked.
Now it's working ok, but i still have the
"AE_NOT_FOUND, Processor Device is not present [20070126]"
warning.
Seems a patch is available here for the warning fix:
http://bugzilla.kernel.org/show_bug.cgi?id=8570
I will try the patch, but as you said is cosmetic. CPU freq is fixed for me.
I just have an issue that i didn't have before:
LC_ALL="C" cpufreq-info
cpufrequtils 002: cpufreq-info (C) Dominik Brodowski 2004-2006
Report errors and bugs to linux@xxxxxxxx, please.
analyzing CPU 0:
driver: acpi-cpufreq
CPUs which need to switch frequency at the same time: 0
hardware limits: 1.60 GHz - 1.86 GHz
available frequency steps: 1.86 GHz, 1.60 GHz
available cpufreq governors: ondemand, powersave, performance
current policy: frequency should be within 1.60 GHz and 1.86 GHz.
The governor "ondemand" may decide which speed to use
within this range.
current CPU frequency is 1.60 GHz (asserted by call to hardware).
analyzing CPU 1:
driver: acpi-cpufreq
CPUs which need to switch frequency at the same time: 1
hardware limits: 1.60 GHz - 1.86 GHz
available frequency steps: 1.86 GHz, 1.60 GHz
available cpufreq governors: ondemand, powersave, performance
current policy: frequency should be within 1.60 GHz and 1.86 GHz.
The governor "performance" may decide which speed to use
within this range.

current CPU frequency is 1.86 GHz.
so seems the cpu 1 from user is always top speed.
The governor i set is ondemand. But seems set only for the first one,
while the second cpu says performance.
So, to resume: 1 issue for the governor for all users, just speed for
the last cpu for simple user and not root.
known issues?
